Breeding the redstriped eartheater

Pairs spawn on a flat stone or in a pit in the sand; the parents then take the eggs or larvae into their mouths (larvophile mouthbrooder), and the young shelter in the mouth at night or when in danger, with parental care lasting several weeks.

Step by step

Pairing

Keep a group of 6 and let a pair form, or one male with several females.

Breeding tank

A 300 L tank with a sponge or gentle filter, fine sand to sift, a few rocks and open swimming space.

What starts it

Clean warm water, big regular water changes and varied protein foods.

Eggs and young

Eggs hatch about three days after spawning (in the parents' mouths). FishBase uses a fecundity of about 250 eggs.

Raising the fry

The brooding parent holds eggs and fry, releasing them at about 1 cm; feed newly hatched brine shrimp.

Common mistakes
  • Coarse or sharp substrate
  • Stressing the brooding fish
  • Infrequent water changes

Male or female

  • Male: Larger with longer fins and a bigger hump
  • Female: Smaller and plainer
  • Males have longer fins

Can I breed it in my tank?

  • Takes some experience.

Day-by-day plan

Typical for mouthbrooders

  1. 21 days beforeGroup and condition

    Usually one male with several females. Feed high-quality food.

  2. Day 0Spawning

    The female takes the eggs into her mouth and stops eating.

  3. Day 21Release

    After about 3 weeks the female releases fully formed fry. Many breeders move her to a quiet tank first.

  4. Day 21First food

    Fry eat crushed flake and baby brine shrimp straight away.

  5. Day 90Grow-out

    Fry are a few centimetres long after about 3 months.

A general guide for this breeding type. Days change with temperature and species.

Stage 1 of 5Group and condition

Usually one male with several females. Feed high-quality food.

Set up a virtual breeding tank and see what would likely happen.

No spawning
  • Without live or frozen food the parents aren't in breeding condition.
